Matching for Music: Speakers or Electronics?

Hello all!

It is generally accepted that there are speakers that match well with certain genres of music as there are electronics (mainly amplifiers) that match well with certain genres of music. My question to you is, given the choice of one versus the other, what would have the biggest impact in terms of sonic “bliss”?

FWIW, I tend to listen to rock (classic rock & alternative), blues & classic jazz 90% of the time, throwing in some orchestral classical music when the mood strikes as the remainder.  
Thanks for any thoughts. Hope you & yours are doing well & staying safe!
